It's not a crime (yet) to innocently dial a wrong number. At least this person had the decency to tell you what happened. Would you have preferred that he or she had just hung up before you answered and not left a message?
There are no other reports concerning this number. If more start coming in, I may reconsider the following comment, but if you get "irritated" by a single one-off wrong number call, you don't have a phone problem. You may have anger management issues.
